Ben 'Relieved' Ex Jennifer Has New Boyfriend: 'This Will Give Him Closure'

Now that Jennifer Garner's new boyfriend has been revealed, Ben Affleck can finally breathe a sigh of relief, RadarOnline.com can exclusively reveal.

The troubled actor, who has had bouts of recent rehab relapses and gal pals, is ready for a healthier change of pace.

"It's good for Ben," said a source. "Friends really think this will give him closure and freedom."

As Us Weekly first reported, the Peppermint actress, 46, has been dating businessman John Miller for about six months. Her younger suitor, 40, is the CEO of CaliGroup, a company that owns Miso Robotics and 50 CaliBurger restaurants.

And the budding romance couldn't come at a better time for the star who just finalized her divorce from Affleck on Oct. 4, three years after they announced their separation.

Since the former pair decided to split in 2015, the Batman star, 46, has struggled to maintain his sobriety and hang on to his longtime girlfriend, Saturday Night Live producer Lindsay Shookus, who called it off with the Oscar winner after he had an affair with Playboy model Shauna Sexton.

But that didn't last long either, with the leading man breaking it off with the 22-year-old in early October.

"Ben's stress levels have been over the top because his crazy love life has been out there and all over the place," said the source. "And he's been in and out of rehab which has gotten tons of attention. Now he's not the only one people are focusing on."

Like Garner, her new beau was also married and has kids.

As RadarOnline.com exclusively revealed, Garner's new CEO beau is still legally married — and in the midst of a nasty divorce.

Miller, 40, and his estranged wife Caroline Campbell have been locked in an ugly battle since first calling it quits on their six-year marriage in 2011. In court docs, Campbell called him "controlling."

But amid the controversy over her new beau, Garner still cares about her ex Affleck and wants him healthy for their three children — Violet, 12, Seraphina, 9, and Samuel, 6.
